interesting.....
Did you ever try the Airbow, Tom? Another trickable quad.
This is an area where we could help each other, the quad-head could show basic quad-line control and you could teach basic trick ideas.

i haven't tried the Airbow, but read about it a long time back. It didn't seem to become the big sensation that some made it out to potentially be. The Tesseract seems appealing; i wonder what the price will be? Robert Randolf (i.e., AudioRob) sure knows how to trick dual line (from the videos i've seen); i'm sure he is a master kite builder par excellence.

Sure we can help each other out with learning!
